The technical system which consists of an Interaction System and a Technological Application System is not cognitive in the sense of Strasser 2004 . The interaction happens in a classical way via a human-machine-interface embedded in the Interaction System. The output of the Technological Application System is evaluated and optimized by the human operator only. This also means that only the human operator can reflect about the output of the Technological Application System and improve it by adapting the parameters of the processes via the human-machine-interface. Fig. 2. Steps in the development of Cognitive Technical Systems The intermediate step middle of the picture is the incorporation of basic cognitive processes in the Interaction System. The technical system could now be accounted for a Cognitive Technical System. The cognitive processes can involve reasoning and decision making. The Cognitive Technical System has to incorporate a knowledge base upon which decisions can be derived. These cognitive processes are embedded in the Interaction System which communicates with the Technological Application System but also controls it. The right part of the picture shows a visionary Cognitive Technical System. Such a system incorporates cognitive processes on all levels which means that the human-machineinteraction is based on multimodal communication. In addition to that the human-machineinterface adapts itself to the mental model of the human operator during the communication process. This increases the efficiency of the communication process dramatically. Therefore the human-machine-interface incorporates cognitive abilities. In addition the Interaction System incorporates cognitive processes in the communication with the Technological Application .
